Drew wants to buy exercise equipment that costs $140 and the sales tax is 5.57% what is the total cost of the equipment

$147.80

Step-by-step explanation:

$140 * 1.0557 = $147.798

5.57% sales tax means $0.0557 added to the dollar

So you would make the percent 1.0557 for 5.57% sales tax

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
